Description
Technical field
This utility patent is related to a kind of three colors double injection machine extrusion die.
Background technology
The demand of existing electric wire is more and more, but present three colors double hyer insulation is also the development of present electric wire
Direction.
Double-layer coextrusion insulated mechanical performance and electric property is better than single layer dielectrics, but double-layer coextrusion insulated Huang now
Green other dichromatic cable speeds of production of double-colored grade are slower, need to be insulating exruded in two times, and once, external insulation once, can go out interior insulation
Existing following point.
1st, insulation is extruded in two times, and primary insulation is extruded once, and outer layer insulation extrudes one layer, greatly reduces the life of insulation
Produce efficiency；
2nd, insulation is extruded in two times, adds mechanical damage number of times of the interior insulation in carrying；
3rd, interior insulation surface impurity and dirt dimly can be increased after interior insulation extrusion when insulation is extruded in two times, so that
External insulation bonds insufficient；
4th, head cleaning time is more, is cleaned once after cable interior insulation extrusion, is cleaned once after external insulation extrusion, significantly
The stability of head is compromised, the efficiency of the production so reduced and production cost is improved.
The content of the invention
It can be noted in order to which the offer of the invention that solves the above problems is a kind of while completing the double-deck three colors bilayer extruded of the color of cable three
Molding machine.
The technical scheme is that：
A kind of three color double injection machine extrusion dies, it is characterised in that including interior mould and outer mold, the interior mold exterior
Provided with casing, current divider in external shunt device, external shunt device inner sleeve is provided with casing, the casing is provided with and is respectively equipped with main feed
Mouthful, the first auxiliary charging aperture and the second auxiliary charging aperture, current divider in the main feed mouthful connection, the first auxiliary charging aperture and second it is auxiliary enter
Material mouth connects external shunt device, and the external shunt device and interior current divider are connected with outer mold.
Further, the external shunt device generally one end is to the tapered bullet type of the other end, the table of the external shunt device
Face is provided with splitter box, and the splitter box includes being provided with vertical block in the transverse groove of the first auxiliary charging aperture of connection, the transverse groove,
The connection end of the first auxiliary charging aperture is provided with blow tank, and blow tank side is provided with opening I, the height of groove where opening I
Slightly above blow tank, the blow tank connects hopper I, and splicing groove I is connected with opening I hopper II, hopper II connection blow tanks,
Side walls of the hopper II close to outer mold side is slightly below the other end, and the hopper I is provided with hopper close to outer mold side
III, hopper III are provided with opening, the auxiliary charging aperture of hopper III connections second close to outer mold side.
Beneficial effect：
Solve three color double hyer insulations and extrude the problem of being changed to once extrude in two times, add production effect during production
Rate；Primary insulation is subject to when avoiding production twice extraneous collision and mechanical damage；Avoid twice production when interior insulation because
There are the phenomenons such as dirt in the primary insulation that the problems such as storage causes；The cleaning time of cable head is reduced, so as to add machine
Head the problem of property.
